NASA got back to me. "The total mass of the Crew Dragon is 26,577 pounds. It will be delivering 449.7 pounds and currently is expected to return 328.5 pounds of cargo, although that is subject to change."

Demo-1: SpaceX Falcon 9 is Vertical at Launch Complex 39A

Anna Heiney Posted on March 1, 2019

The SpaceX Crew Dragon spacecraft is vertical and set for a 2:49 a.m. EST Saturday launch to the International Space Station on the company’s Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. It will be the first time in history a commercially-built and operated American crew spacecraft and rocket launches from American soil.

The Demo-1 mission, SpaceX’s inaugural flight with NASA’s Commercial Crew Program, will provide the teams an end-to-end flight test to ensure the spacecraft and systems operate as designed before launching with astronauts.

Launch coverage on NASA TV and the launch blog will begin at 2 a.m., March 2, followed at 4 a.m. by a post-launch news conference with representatives from NASA and SpaceX. The launch and post-launch news conference also will air on NASA TV.

U.S. Air Force 45th Space Wing meteorologists continue to forecast an 80 percent chance of favorable weather at liftoff.

It seems that number is for the mass at docking so it might actually be heavier than that

Well, after further clarification, the 26,577-pound number is the mass of Crew Dragon at ISS docking. I thought I was clear the first time, but I'm asking again for the total launch mass.

Tower cladding looks very different from this angle and now we know where Elon's watching the launch from:

Published on 1 Mar 2019
NASA Administrator Jim Bridenstine and NASA astronauts assigned to the fly on future SpaceX Crew Dragon missions answered questions from reporters on the eve of the uncrewed launch of its spacecraft on a Falcon 9 rocket, the first launch of a space system designed for humans built and operated by a commercial company through a public-private partnership, on a flight test to the International Space Station. NASA astronauts Bob Behnken and Doug Hurley, assigned to the first flight test with crew, Demo-2, and NASA astronauts Victor Glover and Mike Hopkins, assigned to the first SpaceX Crew operational mission, Dragon-1, shared their thoughts with media about this uncrewed flight test in preparation for their eventual missions on the Crew Dragon. Launch is set for 2:49 a.m. EST on Saturday, March 2 from Launch Complex 39A at the Kennedy Space Center.

T-1 hour to launch, both webcasts should be going live in roughly 10 minutes.

Looks like SpaceX coverage is the same as NASA's.
